Abstract

UN METODO Y SISTEMA PARA DETERMINAR LA SITUACION DEL PRIMER CONDUCTOR AISLADO (10) Y UN CONJUNTO DE CONDUCTORES DE RAMAL SIMILAR (28, 38) QUE SON RAMALES DEL PRIMER CONDUCTOR, PERO SIN CONTACTO OHMICO QUE SE HACE CON LOS PRIMEROS CONDUCTORES. UN MARCADOR PASIVO (16) QUE TIENE UN CIRCUITO RESONANTE QUE INCLUYE UN INDUCTOR Y UN CAPACITADOR QUE SE DISPONE PARA CADA UNO DELOS RAMALES Y QUE SE POSICIONA PARA SER CONDUCTIVAMENTE UNIDO AL PRIMER CONDUCTOR Y AL CONDUCTOR DEL RAMAL ASOCIADO. EL PRIMER CONDUCTOR (10) ES UNA PARTE DE UN CIRCUITO CERRADO Y CADA CONDUCTOR DEL RAMAL ES UNA PARTE DE CIRCUITOS CERRADOS SEPARADOS. UNA SEÑAL ALTERNANTE (14) APLICADA A UNO DE LOS CIRCUITOS CERRADOS ES TRANSMITIDA INDUCTIVAMENTE A CADA UNO DE LOS CIRCUITOS CERRADOS QUE SE UNEN INDUCTIVAMENTE AL MARCADOR PASIVO QUE TIENE UNA FRECUENCIA RESONANTE IGUAL A LA FRECUENCIA DE LA SEÑAL ALTERNANTE. EL FLUJO DE SEÑALES ALTERNANTES EN LOS BUCLES CERRADOS Y LOS MARCADORES PASIVOS PRODUCE UNA SEÑAL ELECTROMAGNETICA DETECTABLE QUE SIRVE PARA IDENTIFICAR LA SITUACION DEL PRIMER CONDUCTOR, CUANDO LOS CONDUCTORES DE LOS RAMALES Y LOS MARCADORES PASIVOS CONDUCEN LAS SEÑALES ALTERNANTES.
